RAID | NAS | data recovery prices

Guide prices (net ranges) – RAID | NAS data recovery fee net: from 100.000 HUF
  • Baseline / minor logical issue (e.g., RAID 1 or stable RAID 5, damaged file system but readable members) net: HUF 100.000 – 180.000
  • More complex recovery (e.g., RAID 5 with one failed and multiple weak members; RAID 0 parameter inference; NAS metadata corruption) net: HUF 180.000 – 350.000
  • High capacity / multiple concurrent faults (e.g., RAID 6 with several weak disks, long fault-tolerant reads) net: HUF 350.000 – 600.000



A bevizsgálási díj 50.000 Ft + Áfa, leadáskor fizetendő, melyet elfogadott árajánlat és sikeres adatmentés esetén beszámítunk az adatmentés költségébe.

Estimated turnaround is 1–3 business days, but may be longer for higher capacities.

"No data – no fee" policy: if we cannot deliver usable data, the recovery labor fee is not charged (diagnostics and any logistics/parts costs are separate items).

 
How does RAID data recovery work?
  • Safe diagnostics (write protection): each member disk is connected individually with no write operations, and its condition is assessed.
  • Disk imaging: a separate, fault-tolerant, sector-by-sector image is made from every member (handling bad sectors, retries).
  • Array reconstruction: we reassemble the array from the images in software (RAID level, stripe size, order, offset, parity direction).
  • File system recovery: the file system is recovered from the virtually reconstructed array (NTFS, ext4, Btrfs, XFS, ZFS, etc.).
  • Verification and delivery: critical files are sample-opened for verification, then data is delivered (on a new drive or via encrypted download).
  • Very important: do not start a rebuild, do not initialize the array, do not change disk order, and do not run “repair” tools — these can significantly reduce the chances of success.


Typical scenarios and options

  • RAID 1 (mirror): often recoverable even with one failed disk; we image the good member and recover directly from it.
  • RAID 0 (stripe): a single disk loss is critical; we infer parameters from remaining members and metadata, then assemble the data.
  • RAID 5: one disk loss is tolerated, yet data can still be affected in degraded mode. After handling the bad disk and weak sectors, we rebuild parity virtually to reconstruct the array.
  • RAID 6: two disk losses are tolerated; more complex but often recoverable if the remaining members are imageable.
  • RAID 10 / 50 / 60: due to combined mirror + stripe, a tailored strategy is needed; first image all members, then reconstruct layer by layer.
  • NAS enclosures (Synology, QNAP, TrueNAS, etc.): we also restore NAS-specific metadata (e.g., mdadm, LVM, SHR, Btrfs) and perform file-system recovery on the virtually reassembled volume.

Frequently Asked Questions

Write-blocked diagnostics on every member disk → individual, fault-tolerant disk images → logical reconstruction of the array (RAID level, stripe, order, offset, parity) → file-system recovery (NTFS, ext4, Btrfs, XFS, ZFS, etc.) → sample-open verification → delivery.

  • Baseline / minor logical issue (e.g., RAID 1, stable RAID 5) net: ~ HUF 100.000 – 180.000
  • More complex recovery (e.g., RAID 5 with weak sectors, RAID 0 parameter inference, NAS metadata fault) net: ~ HUF 180.000 – 350.000
  • High capacity / multiple faults at once (e.g., RAID 6 with several weak disks) net: ~ HUF 350.000 – 600.000

 

Diagnostics: HUF 25.000 + VAT (credited if successful). Urgent diagnostics: HUF 35.000 + VAT. "No data – no fee": if no deliverable data can be produced, the recovery labor fee is not charged.

RAID 0, 1, 5, 6, 10, 50, 60, plus vendor/NAS-specific schemes (e.g., Synology SHR/SHR-2, mdadm + LVM, ZFS vdevs, Btrfs multi-device). We always reconstruct the array virtually from disk images.

Do not start a rebuild, do not initialize the volume, do not shuffle disk order, do not run “repair” tools, and do not write to the array. Any writes reduce the chance of success.

Often imaging the healthy member with write protection is sufficient, then recovery proceeds from that image. The failed member is examined separately; working from the good image minimizes risk.

Difficult, but often yes. We infer stripe size, order, and offset from the remaining members’ images; if the failed disk is partly readable, specialized reading strategies may help fill gaps.

Image all members → read weak/bad disks gently → virtual parity reconstruction (RAID 5 tolerates 1 failed, RAID 6 tolerates 2) → file-system repair/extraction from the virtual array.

NAS-specific metadata (mdadm, LVM, SHR, Btrfs/ZFS). We image the member disks separately, then assemble the volume from those images. All work is performed outside the NAS in a safe environment.

Generally yes, if the password/key/recovery key is available. Without the key, contents cannot be decrypted; even with a key, a maximally complete raw sector image is critical.

Depends on capacity and condition. In baseline cases 1–3 business days,; for weak sectors/large volumes it can be several days to weeks due to careful, repeated reads.

Yes. For urgent cases we prioritize diagnostics and critical steps; extra costs and expected turnaround are agreed in advance (urgent diagnostics: HUF 35.000 + VAT).

Often yes, especially with RAID 6 / RAID 10. Success hinges on gentle imaging of all members and precise logical reconstruction. We estimate final odds after diagnostics.

On a new external drive, onto a NAS, or via encrypted download link. We can preserve the folder structure and provide a file list/report on request.

„No data – no fee”: if no deliverable data is produced, the recovery labor fee is not charged. Diagnostics, logistics, and any parts costs are billed separately.

Stop all load, do not start a rebuild, note the disk order and status, take a photo of the NAS status page, then contact us. Fast, professional intervention is crucial.
